Macro and micro morphology, heat transfer mechanisms, and in-plane heat leading performance of CBCF/SiBCN composites

Caption

The CBCF/SiBCN composite is characterized by its lightweight and porous structure, featuring a visible heat-leading layer in its cross-section. Microscopic analysis reveals that the ceramic matrix fills the voids within the CBCF framework and encapsulates the carbon fibers, resulting in a tightly bonded interface. The development of the heat-leading layer enhances thermal dissipation capabilities, as evidenced by a more uniform temperature distribution and a reduction in localized thermal stress. This material demonstrates significant potential for thermal management applications.
